Eletrical wirings

Hi Volker
Yes i understand about the coax Cable. But in page 4 and 5 (General discription....) the cable goes trought terminal 7.
But not in page 6 and not in my case. Are you talkin about pin 7 and terminal 7 in same way? I think that cable from ignition switch gear (TD) i can understand and recognize. (I dont have rpm meter in my car) But i have a 2 pinth connector shown in some page. There is one cable from (maybe) direct "from start run bus" to terminal 7, maybe it is the cable shown in the wiring diagram, goes before the first preresitor, direct to, terminal 7? And if so where is that cable connected? To the cluster or to the igintion switch or to elsewhere. Can i take it away. The cable is all burned, the covering. But no one of the near cables seems affected. But i havnt found it under the dashboard, behind the cluster. So i´m not sure, affected or not? My alternator is repaired, all the diods and coil where brokened. And before install all i want to be sure. What do you think?
Many thanks and regards /David

The green cable ends up in pin 7 of ignition module. That is not terminal 7 on that drawing! Terminal 7 somewhere connects TD signal. If you have no rpm meter, you can simply disconnect TD.

Thanks, finally I understand. The problems I had, is regarding to the TD-signal. It goes from ignition module and not in the opposite direction, that I first thought. And it is only connecting in terminal 7.
Where can I see, which and where to find the different terminals, is that obvious in the wiring diagrams? is it only me? I find it rather difficult to find them (and also vehicle location).
A another problem for me, I don't see different colors (I'm color blind)

But again, thank you Volker

Hi David,

I am sorry, I don't own a W116. So I cannot help on location of terminal 7.
